PERFORATlNG-STAM P.

SPECIFICATION forming part of Letters Patent No. 249,975, dated November 22, 1881.

Application filed January 26, 1881. No model.)

To all whom it may concern:

Be it known thatI, HENRY H. NoRRrNGToN, of West Bay City, in the county of Bay and State of Michigan, have invented a new and useful Improvementdn Perforating-Stamps; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object of my invention is to provide an improvement in the class of punches or perfo rating-stamps designed for use in banking and other similar establishments for the purpose of puncturing or cutting out portions .of a check or other written instrument, and thereby preventing fraud by alteration of such instrument to cause it to express a higher value than was originally intended.

I have obtained Letters Patent of the United States for stamps or punches of this class, and the present invention is in the main an improvement upon that which forms the subject of Patent No. 223,161, granted to me on December 30, 1879.

The changes in construction and the new or added devices embodying the improvements will be hereinafter described in detail, reference being bad to accompanying drawings, forming part of this specification. I

Figure 1 is a plan view, part of the head of Fig. 2 is a showing also a check or other paper secured on the table. Fig. 3 is a vertical longitudinal section on line 9 y, Fig. 1. Figs. 4. and 5 are plan views of the under and upper sides respectively, of the disk to which the receiving dies are attached. Fig. 6 is aplan view of the base of the stamp and the devices directly attached to it. Fig. 7 is a section on line 22, Fig. 6. Fig. Sis a detail sectional view, showing the attachment of the punches to the carrier.

The letterAindicatcs the table upon which the check or other paperXislaid to be punched, and over which it is drawn from right to left by means of a feed-wheel, B, the paper being guided in such movement in a right line by fingers a, that are adapted for adjustment toward or from the front edge of the table. The said wheel 13 is arranged vertically beneath the table A, and its roughened periphery works through a lengthwise slot in the same. The

paper is held down on the wheel by a springpresser, C, so that it will have the requisite frietion therewith to insure the required feed, or intermittent progressive movement imparted to it by devicesoperated by the plunger E. From the baseD of the stamp rises a tubular standard, in which said plunger E is arranged to slide vertically.

The above devices were embodied in my previous inventions, although in somewhat different form.

1 will now indicate the additions and changes I have made in the construction and consequent operation of the stamp.

The plunger E is passed centrally through and is connected by groove and feather, Fig. 2, with a disk, F, that carries a series of vertical punches, 1), arranged concentrically with its axis.

Directly above and parallel to the disk or punch carrier F is a second disk or punch receiver, F, which is provided with a series of holes, Z), arranged concentrically with the aXis, and also coincidently with the position of the several punches b. These two disks F F are rigidly connected by a central tube or hub or in any other suitable manner, and hence rotate together and with the plunger E, the latter being also free to slide vertically within the limits defined by the feather and groove; hence by turning the enlarged milled head 0 of the plunger E the disks F F can be set in any required position.

The punches b are small solid cylinders and slide vertically in their sockets. They project about one-third their length below the carrier F and are encircled by spiral springs c, which are fastened to the punches at the lower end. The function of these springs is to retract the punches after having punched the paper.

To the under side of the upper disk, F, Fig. 8, are permanently attached a series of dieplates, one for each hole I) in the disk. These plates are cut with the figure of a star and numbers from one to nine, inclusive, and also the cipher, (0.) On the upper side of the disk F the same characters are inscribed, Fig.3, immediately contiguous to the several holes I), which correspond to the dies or die-plates. This inscription is for convenience of inspection by the operator, so that he may always quickly adjust the die-carrier F to bring the required punches b successivelyto the front, in which position alone they can be operated to puncture thepaper.

The heads of the punches b are cut with the same characters (stars and numerals) as the aforesaid die-plates or dies and are also adapted to fit accurately in the latter, but free to slide vertically, so that it may be forced up or through the paper placed between the disks F F. The device for raisin g the punches to cause them to do this work is a lever, H, which is pivoted on the bed of the stamp so that its head projects under the plunger E, which rests thereon. This same arrangement was exhibited in my previous invention; but I have in this case provided a different form of spring, and also arranged it differently. Likewise, by the projection of the punches 1) below their carrying-disk F, I am enabled to dispense with a finger or vertical projection on the front portion of the lever, which was previously required for the purpose of forcing up the punches. I further simplify the construction by employing but one spring in place of twothat is to say, I employ a plate-spring, I, which is placed in guides or keepers d on the bed M of the stamp and arranged at right angles to the lever H. This spring is arched or curved upward, and hence presses upward against the head of the lever H, so that the free or front end of the latter is depressed and the plunger E held normally elevated. When the plunger is forced down the spring I yields or bends downward and the lever H is tilted, thus bringing its free end up against a punch, b, and forcing it through the paper, as will be readily understood.

The front end of the lever H has a lateral arm which is connected with the feed-wheel B by. means of a pawl and ratchet. The improvement over my former invention consists in this. As before, the ratchet forms an integral portion of the feed-wheel B, or is else rigidly attached to it but, instead of providing it with teeth on its periphery, the teeth f are formed on the side of the same contiguous to its edge and the pawl g is pivoted to swing laterally and held against the face of the wheel by a spring, 71, so that each time the lever H rises to force up a punch, b, the pawl g slides up and hooks over a tooth, f, and as the lever H resumes its original position the pawl draws down the tooth it has thus engaged, and thereby rotates the wheel B and moves the paper a corresponding distance over the table A.

This arrangement of parts-to wit, ratchet,

pawl, and spring-insures their operation or regular coaction, so as to feed the paper in the required manner, whatever be the speed or irregularity with which the stamp is operated.

Another improvement consists in applying a platespring, L, as shown in Figs. 2 and 6, so that it will not only serve as a stop to arrest the motion of the punch-carrier F and hold it steady in the required position, but

also announce to the operator, by a clicking sound, when the carrier is properly adjusted with a punch, b, in front. Such spring L is secured at one end to the base M, and its free end is bent or curved sharply upward to form a projection of suitable form to enter between the ends of the punches b. When the die or punch carrier F is rotated the punches pass over the end of the spring and depress it; but at each such passage a click or sharp sound is produced.

Afurther improvementconsists in constructing the thumb lift or plate of the clip or presser with a rear extension, which projects beneath the rim of the disk or receiving-die F. Fig. 1., so that the thumb-lift cannot be raised so high as to weaken the spring, and thereby render it useless for its purpose. This feature is of much importance in the practical use of the stamp.

I have also devised a new mode of securing or attaching the punches b to the disk or carrier F.

As shown in Fig. 8 the punches are provided with lateral studs l, and the carrier with vertical slots m, to receive the same. The slots open into the sockets of the punches and extend nearly to the top of the carrier, so that they limit the upward movement of the punches, as well as prevent their rotation.

To hold the punches b in their sockets and resist the tendency of the springs cto draw them downward, I apply a wire or other small band, a, to the carrier F, the same fitting in a circumferential horizontal groove in the latter, as shown. This means secures the punches, and yet permits them to be conveniently removed when required.

Having now described my several improvements, I claim them as follows:

1. The combination, with the table and receiving-die, of the spring clip or presser having a thumb-lift which extends inward beneath the edge of the die, as shown and described, for the purpose specified.

2. The combination of the rotating punchcarrier, the punches whose lower ends project below its under side, the springs encircling such projecting portions of the punches, and the lever arranged as shown, and having a flat head that acts on said punches for forcing them up at the proper time, as set forth.

3. The combination of the punch carrier having sockets and vertical slots opening into the same, the punches provided with studs that project into and slide in the slots, and a band which encircles the carrier and prevents detachment of said punches, as well as supports them when not in action, as and for the purpose specified.

4.. The combination, with the plunger and rotating punch-carrier, the punch-lever H, and bed M, having pairs of keepers d, as specified, of the spring I, which is constructed of an arched metal plate and held in place by said IIO IIS

keepers that embrace or form sockets for its H, the pawl g, hinged thereto so as to swing l side of the same, of the spring arranged, as 10 laterally, the ratchet or hooked disk having specified, to serve as a stop and produce a click teeth f projecting laterally from its inner side, to announce when the carrier is in proper pothe spring for holding the pawl pressed latersition for operation.
